Is it possible to enable users to change their password in ther user options? My server can't send email so using Special:PasswordReset isn't possible. I'm not a 100% sure if I haven't accidentally disabled password changes.

Yes, the password can be changed in the Preferences, see Help:Preferences#Change_password. When you think you might have disabled that setting, enable it again. One way is $wgHiddenPrefs.
